For Base: In a large microwavable bowl, microwave butter or margarine on High until melted, about 1 minute. Blend in cocoa, sugar, egg, and vanilla extract. Microwave, uncovered, for 1 minutes, stirring after 30 seconds. Mixture will resemble custard. Chop nuts on the STEEL BLADE with 6 or 8 quick on/off pulses. Add nuts, graham wafer crumbs or granola and coconut to microwaved mixture; stir well. Press evenly into a sprayed 9-inch square pan.

For Filling: Process all filling ingredients until well mixed, 15 to 20 seconds. Scrape down sides of bowl as needed. Spread filling evenly over base. Chill for 15 minutes.

For Glaze: Microwave chocolate and butter or margarine on Medium (50%) for 2 to 3 minutes, until melted, stirring after each minute. Let cool for 10 minutes. Pour Glaze over filling. Tilt pan back and forth so that glaze coats evenly. Chill. Cut into squares.
